arm: add initial support for Amlogic P212 based on Meson GXL family

Browse Source 
This adds platform code for the Amlogic P212 reference board based on a
Meson GXL (S905X) SoC with the Meson GXL configuration.

This initial submission only supports UART and MMC/SDCard, support for the
internal Ethernet PHY in Work In Progress.

U-Boot for Amlogic P212
=======================
P212 is a reference board manufactured by Amlogic with the following
specifications:
- Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz
- ARM Mali 450 GPU
- 2GB DDR3 SDRAM
- 10/100 Ethernet
- HDMI 2.0 4K/60Hz display
- 2 x USB 2.0 Host
- eMMC, microSD
- Infrared receiver
- SDIO WiFi Module
- CVBS+Stereo Audio Jack
Schematics are available from Amlogic on demand.
Currently the u-boot port supports the following devices:
- serial
- eMMC, microSD
u-boot compilation
==================
> export ARCH=arm
> export CROSS_COMPILE=aarch64-none-elf-
> make p212_defconfig
> make
Image creation
==============
Amlogic doesn't provide sources for the firmware and for tools needed
to create the bootloader image, so it is necessary to obtain them from
the git tree published by the board vendor:
> wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz

> git clone https://github.com/BayLibre/u-boot.git -b n-amlogic-openlinux-20170606 amlogic-u-boot
> cd amlogic-u-boot
> make gxl_p212_v1_defconfig
> make
> export FIPDIR=$PWD/fip
Go back to mainline U-boot source tree then :
> mkdir fip
> cp $FIPDIR/gxl/bl2.bin fip/
> cp $FIPDIR/gxl/acs.bin fip/
> cp $FIPDIR/gxl/bl21.bin fip/
> cp $FIPDIR/gxl/bl30.bin fip/

> cp u-boot.bin fip/bl33.bin
> $FIPDIR/blx_fix.sh \

> $FIPDIR/blx_fix.sh \

fip/zero_tmp \
fip/bl2_zero.bin \
fip/bl21.bin \

bl2
> $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
> $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
> $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin

--bl30 fip/bl30_new.bin.enc \
--bl31 fip/bl31.img.enc \
--bl33 fip/bl33.bin.enc
and then write the image to SD with:
> DEV=/dev/your_sd_device
> dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
> dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
